Earlier this week, in a beautiful garden in Woodside, Ca., the team at the five-year-old, seed-stage venture firm Pear hosted it fifth annual demo day. It’s an event that’s limited to roughly 100 VCs who year after year happily fill the space to see what Pear — which has written early checks to the “unicorn” delivery service DoorDash and newly public Guardant Health, among others — has up its sleeve.

As with last year, what those investors wound up seeing on Tuesday was 15 teams, most of them six months old or younger and led by current students or recent graduates who’d been invited by Pear to build companies over ten weeks in its Palo Alto offices. These ranged from a startup with ambitious plans to build a new commercial space station, to a machine learning-powered cloud video platform that makes it far easier to edit video clips, to a startup that uses AI to negotiate salary discussions on behalf of its clients.

But in a bit of a twist, this time around, Pear also featured a sprinkling of young companies that are now ready for Series A funding, including a solar design and sales platform for residential and commercial photovoltaic systems, and a company that thinks its check-out free shopping technology could help all kinds of Amazon rivals compete with the giant’s growing number of surveillance-powered, no-checkout convenience stores.

In case you’re an investor or just someone interested in keeping your thumb on the pulse of what’s happening in emerging tech, herewith is a quick snapshot of each of the companies that were featured as part of the program. (Well, all but one that expressly asked us not to write about what it’s working on. We’ll just tell you that it’s a kind of social network and, remarkably, it feels fresh.)

If you’re interested in reaching out to any of these folks, you can find of all of their email addresses here.
